Abstract
Control systems, methods and fully regenerative power conversion systems are presented for mitigating common mode voltages in AC loads by employing inverter and/or active rectifier PWM control using switching sequences with only active vectors where a first vector of each switching sequence differs by one phase switching state from a last vector of a switching sequence of an adjacent sector.
